CHARLES A. BELL, OF DICKEY, NORTH DAKOTA.

GRAIN-DOOR.

To all whom it may concern:

Be itknown that I, CHARLES A. BELL, whose post-ofiice address is Dickey, North Dakota, a citizen of the United States, residing at Dickey, in the county of Lamoure and State of North Dakota, have invented certain new and useful Improvements in Grain-Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved grain door for cars, and to this end the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, in which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings,Figure 1 is a view showing the improved grain door in side elevation applied in working position to the door opening in a car body, some parts of the car body being broken away; Fig. 2 is a view corresponding to Fig. 1 but looking at the same from the inside of the car, some parts of the car body being shown in section, and some parts being broken away; Fig. 3 is a view corresponding to Fig. 2 with the exception that the grain door is shown in a different or idle position; Fig. 4 is a view in transverse vertical section taken on the line w w of Fig. 1; Fig. 5 is a detail view, on an enlarged scale, with some parts sectioned on the line 219 :0 of Fig. 2; Fig. 6 is a detail view, on an enlarged scale, principally in section, taken on the line x w of Fig. 3, and, Fig. 7 is a detail view, on an enlarged scale, showing the lock for the supplemental grain door.

The numeral 1 indicates a portion of a car body having at its sides the usual door openings formed between the door posts 2, only one of which door openings is shown. Each door opening is adapted to be closed by means of a main grain door 3 and a supplemental grain door 4. The supplemental grain door 4 is carried by the main grain door 3 and is secured thereto with freedom for vertical sliding movement by means of a metallic bracket 5. This bracket 5 is, as shown, preferably made up of three laterally spaced and vertically extended bars con- Specification of Letters Patent.

nected at their lower ends and terminating at their upper ends in hooks 6. These hooks embrace the upper edge portion of the main grain door 3 and are permanently secured thereto by means of rivets or otherwise. The bracket 5, at its horizontal intermediate portion, is first bent laterally outward a distance substantially equal to the thickness of the supplemental grain door 4 and is then bent downward parallel to the main grain door 3, thereby leaving the depending portion of the bracket 5 spaced apart from the main grain door 3. The supplemental grain door 4 is mounted between the off-set por tion of the bracket 5 and the main grain door 3, and is secured to the bracket 5 by means of a guide loop 7 whichis secured at its ends to the supplemental grain door 4 with its intermediate portion embracing the central member of the bracket 5 and adapted to slide thereupon. The supplemental grain door 4 is held in. an upper or inoperative position by means of a sliding bolt 8 mounted in the guide loop 7 for move ments into and out of engagement with a seat 9 formed in the central member of the bracket 5.

The main grain door 3 is suspended in an elevated position above the floor of the car body 1, for endwise and for end-for-end movements as the same is moved from operative to inoperative positions and vice versa by means of a chain 10, having at each end a ring 11, and which rings are secured to the two outer hooked ends 6 of the bracket 5. To the intermediate portion of the chain 10 is swiveled a ring 12, and which ring is mounted for sliding movement on a long horizontally extended rod 13 secured above the door opening and extending to one side thereof.

On the outer face of the main grain door 3 is secured a pair of vertically extended lock strips 14 that are located one near each end thereof, and on the inner face of said door directly opposite the lock strips 14 is secured a second pair of lock strips 14. These look strips 14 and 14 are permanently secured to the main grain door 3 by means of rivets or otherwise and their ends extend both above and below the upper and lower edges of the main grain door 3, the purpose of which will presently appear.

In the inner faces of the door posts 2 is formed a pair of long, narrow and vertically extended lock seats or grooves 15 and 1G, and in the inner face of one of the vertical posts 1 of the car body 1 is formed another or third lock seat 17. The lock seats 15, 16 and 17 are all alike and are equally spaced apart, and their extreme end portions are closed by means of plates 18 secured to the door posts 2 and the post 1 and thereby form, in each lock seat, a pair of oppositely projecting lock pockets 19.

To the outer face of the supplemental grain door 4 and near each end thereof is secured by rivets or otherwise a vertically extended lock strip 20. These lock strips are adapted to be seated for vertical sliding movement, when the main grain door 4 is in an operative position, in a pair of lock seats 21 formed in a pair of supplemental door posts 22, secured one to each of the door posts 2. The supplemental grain door 41- is of substantially the same length as the width between the door posts 2 and works between the lock strips 14 of the main grain door 3.

Secured to the lower edge and intermediate portion of the supplemental grain door 4- is a plate o3, having an opening in which may be inserted a suitable tool, such as a crowbar, for the purpose of lifting the supplemental grain door 4 above the floor of the car body 1, in order to release the con tents within the car body 1, and thereby relieve the pressure on the main grain door 3.

The lock seats 15 and 16 are adapted to receive the lock strips 1 1 of the main grain door 3 when the same is in an operative position to close the door opening, as shown in. Figs. 1 and 2, and in which position the projecting ends of the lock strips 141 extend into the lock pockets 19 and thereby secure the said door in position. When the main grain door 3 is in an inoperative or idle position, the lock seats 16 and 17 are adapted to receive the lock strips 14 of the said door with their projecting ends extending into the adjacent lock pockets 19. The distance between the upper and lower pockets 19 is slightly greater than the width of the main grain door 3, and the depth of the pockets 19 is such as to permit slight vertical movement of the lock strips within the lock seats.

To remove the main grain door 3 from either an operative or inoperative position, the said door is first moved slightly upward a distance sufiicient to withdraw the lower ends of either the lock strips 1 1 or M from the lower pockets 19, and then by a slight downward movement of the grain door 8 the upper ends of either the lock strips 14 or 1 1 are withdrawn from the upper lock pockets 19, thereby releasing the said door.

The above device, while extremely simple and of comparatively small cost, is thought to be highly efficient for the purpose had in vlew.

In some instances, the above described device may be used as an end gate in wagon grain tanks.

WVhat I claim is 1. The combination with a car body having a door opening, of a grain door for said door opening, reversely extended upper and lower lock projections secured to said grain door, and upper and lower vertically spaced lock pockets in said car body adapted to receive the said lock projections for holding said grain door in an operative position, said upper lock projections and cooperating lock pockets being comparatively long in respect to said lower lock projections and cooperating lock pockets, substantially as described.
